Can't install latest nuget package

[johanrex]

I'm using VS2017 and .NET Core 2.0. I have downloaded and installed "dotConnect for Oracle 9.4 Professional Trial". After that I added the nuget package Devart.Data.Oracle 9.4.348 to a new console project. This is the output from the package manager:

As you can see it has rolled back the package and not added the dependency. Why is that? Is it possible to use your dotConnect for Oracle on .NET Core 2 to talk to an Oracle 11/12 database?

Thanks

1. dotConnect for Oracle v9.4.348 supports .NET Standard 1.3 (.NET Core 1.3). We will notify you when .NET Core 2.0 support is implemented. An approximate timeframe is one month.

2. We have reproduced the issue with references mismatch. As a workaround, right click project in Solution Explorer > Properties > Build > Treat warnings as errors > Specific warnings and remove NU1605 from the list.

Great. I got it working by targeting .NET Core 1.1 on win 10.

Can I expect this to also work on linux? I.e. are there any platform specific code that need special attention?

Yes, it should work, trial licensing on Linux: https://www.devart.com/dotconnect/oracl ... ndard.html.

.NET Core 2.0 is now supported: viewtopic.php?f=1&t=36128.
